<td> There is a workaround using ImageBitmaps to extract a subregions of the source image. The workaround does not solve cases where sub-region extraction needs to be synchronous either because the source image content changes over time (e.g a canvas or video), or because the subrectangle coordinates cannot be determined in advance.

There are features that have been requested, but for which we are lacking implementor interest. Without two or more vendors interested in implementing the feature, they are unlikely to get added to the specs.

Needs detailed specification work to describe what happens with scripts running in the prerender context (since normally scripts can't run in non-active documents, and normally there's only one active document per session history).

There is a workaround using ImageBitmaps to extract a subregions of the source image. The workaround does not solve cases where sub-region extraction needs to be synchronous either because the source image content changes over time (e.g a canvas or video), or because the subrectangle coordinates cannot be determined in advance.
